This invention relates to improvements in striker plates for use in connection with the latch bolts ofvdoors and more particularly the invention contemplates a striker plate of this type in which the stop of the striker plate is adjustable to take up the play or lost motion between the sto and the latch in order to prevent the door rom rattling.

One object of the invention is a striker 13 plate of the type generally described which when adjusted will function in the manner desired While permitting, to an appreciable extent, expansion, contraction or warping of the door or its casing.

A further object is the striker plate in which the latch stop may be adjusted while thedoor is closed.

A still further object is a construction in which the door can beclosed easily to its latched position.

The invention is illustrated in the accom panying drawing, in which Figure 1 is a front View of the striker plate as applied to a door jamb. Figure 2 is a transverse section of the same taken along line 2-2' of Figure 1, the latch and associated parts of the door being indicated in dotted lines.

Figure 3 is a side View of the striker plate and associated portion of the door jalnb.

As illustrated, the striker plate 5 is formedwith openings 6 and 7 which receive, when in projected positions, the latch and bolt rer spectively, of the door 8. The door jalnb is cut away as at 9 to provide the usual opening behind the striker plate, the latter having laterally extending portion 10, adjacent the opening 6 over which the latch 11 rides as the door approaches and moves to a closed position. The central inner part of the laterally extending portion 10 is bent rearwardly from the plane of the face of the plate to provide a rib 12, the deformation of the plate in this manner providing a reduced opening 13 which is a continuation of the latch openhe rib 12 serves tosupport an element 14 which, as illustrated, is threaded at its outer end as at 15 and has a smooth inner end 16, the terminal portion of thelatter being tapered as at 17. The element 14 is preferably supported by the rib 12 to extend angularly in the direction of its smooth end toward the opening 6. At its smooth end it is formed with a flat face 18 which is designed to eooperate with the latch 11 of the door, when the latter is in its closed position, to engage the back of the latch and hold the doorsecurely and prevent its rattling.

In order to adjust the element to position its 511 face 18 in the desired relation to the door latch, it is formed at its outer end to co-operate with a suitable tool as, for example, a screw driver. In this connection, it will be noted that the element lies in a laterally extending passage 19a which is a continuation of the opening 9, the said passage extending to the face of the jamb and the operating end of the element being accessibletherethrough. By virtue of this construction, the element 76 is accessible while the door is in its closed position and hence a quick and accurate adjustment may be made.

The element 14 is preferably designed so that the upper side of the tapered end will lie, at the outset, in the same plane as the face of the striker plate. Thus, as the opening 13 provided by the formation of the rib 12 is of less width than the latch 11, the latter, as the door is closed, rides first over the strike surface 10 of the plate and then continues over the tapered end 17 of the element without encountering any projections. During adjustments, the tapered end 17 may, of course, be moved slightly laterally rela- 35 tive to the face of the striker plate, but any such movement will be relatively small because of the small angle at which the element is inclined.

As the element 14: is inclined toward the latch opening 6, the face 18 thereof will be presented to the latch at an angle, that is to say the face will be inclined from its rear edge in the direction of its forward edge away from the rear face of the latch, the angle at which the strike face is presented to the eo-operating face of the latch being substantially less than 90 in order that as the latch engages the forward edge of the strike face it will slide easily over the said face toward and beyond the rear edge thereof. This has the advantage that when the element has been adjusted to the position desired and the door is closed the latch will 5 readily pass the forward edge of the face 18 and will not engage the element until it approaches the rear edge of the face.

A further advantage obtained b this construction is that when once the e ement has been adjusted, it will function to prevent rattling of the door while at the same time permitting, to an appreciable extent, expansion, contraction or warpin of the door or the casing, any such change in the door or its casing merely resultin 1n a change of the point at which the late first engages the inclined face of the element.

. The invention is illustrated and described in connection with a striker plate in which 90 an integral portion thereof is utilized to provide a support for the adjustable element. It will be understood, however, that the invention is equally applicable to various forms of door keepers regardless of the manner in which the adjustable stop is supported.

I claim as my invention:

1. In a striker plate formed with a'latch receiving opening, the combination with an element having smooth and threaded portions the former providing a strike face which is accessible through said opening, said threaded portion enabling adjustment of the said element to vary the position of the strike face relative to said latch.

2. In a striker plate formed with a latch receiving opening, said plate having a rearwardly extending rib, the combination with an element threaded on one end and smooth on the other and formed at the smooth end 4. with a strike face which is presented at an angle to the latch of the door, said threaded portion enabling adjustment of the said element to vary the position of the strike face relative to said latch.

v 3. In a striker plate formed with a latch receiving opening, the combination with an element supported by and behind said plate and formed with a flat strike face which is substantially perpendicular to the axis of the element and which is presented to, the

latch through said opening, said element having a face inclined toward said opening substantially in the plane of the striker plate and slidably engageable by the latch duri its closing movement, said element being a ustable axially in such sition, whereby the said strike face of the e ement is resented to the co-operating face of the etch at m angle of substantia ly less than 90 in the various 'tions to which the element is ad'ustab e. v
